Spectral Distortion Anisotropy from Inflation for Primordial Black Holes
David Zegeye, Keisuke Inomata, Wayne Hu
Single field inflationary models that seek to greatly enhance small scale power in order to form primordial black holes predict both a squeezed bispectrum that is enhanced by this…
Amplification of Primordial Perturbations from the Rise or Fall of the Inflaton
Keisuke Inomata, Evan McDonough, Wayne Hu
The next generation of cosmic microwave background, gravitational wave, and large scale structure, experiments will provide an unprecedented opportunity to probe the primordial pow…
Bound on Induced Gravitational Waves during Inflation Era
Keisuke Inomata
We put the upper bound on the gravitational waves (GWs) induced by the scalar-field fluctuations during the inflation. In particular, we focus on the case where the scalar fluctuat…
Primordial Black Holes Arise When The Inflaton Falls
Keisuke Inomata, Evan McDonough, Wayne Hu
Primordial Black Holes (PBHs) have entered the forefront of theoretical cosmology, due their potential role in phenomena ranging from gravitational waves, to dark matter, to galaxy…
